` i To all fw hom it may concern Be it known that I, VicToRCARoUso, a citizen of the United States, residing at Oakland, in the county oflameda and State of California, have invented certain new and useful-Improvements in Batteryl Switch-Locks, of which the following is a specification.

My invention is a battery switch .lock particularly useful forlockingthe ignition and lighting and starting circuit of an automobile out of operation.

Referring to the annexed drawing which forms a part of this specification:

Figure 1 is a side view of inylock.

Fig. 2 is a rear view thereof.

Fig. 3 is a cross section kof my lock takenV on line 3-3 of Fig. `1 looking toward the .i i front of the lock. i 2()` Fig. 4 is a cross section of my lock taken on line 3-3 of' Fig. 1 looking toward the rear of the lock. g

Fig. 5 is a diagrammatic view of an automobile ignition and lighting circuit con-A trolled by my switch.

In the drawing 1 indicates a` front plate and 2 a rear plate which are connected by four rods 3 spaced apart at points correspending to the corners of the plate 2. Two 30 socket switch contacts 4 are mounted on the inside of the plate 2, from the rear of which contacts extend binding posts 5 through openingsV 6 in said plate. Insulating bushings 7 iit in the openings 6, and have flanges 8 which engage the inner surface of plate 2, the binding posts 5 extending through said bushings with the inner end of the socket V'contacts 4 engaging said flanges. Washers `9 of insulation ft on the binding posts 5 against the rear surface of the plate 2. Nuts 10 screw on binding posts 5 against the washers 9. The wire terminals 11 are clamped on the binding posts 5 between the nuts 10 and nutsl2 which screw on said binding posts against said terminals.

i 'A studv 13 which extends through the upper part of front plate 1 is slidably mounted in a bearing 14 on said plate and carriesv on its rear end a bus bar 15 which Specification of Letters Patent.

in turn carries two rearwardly extending switch contact pins 16 in alinement with sockets 4, A head 17 is secured on the front end of stud 13.

Inthe lower part of the front plate 1 is Vmounted a standard Yale lock 20 having a swinging arm 21 in the rear `thereof,the end of which is adapted to swing in the rear of the bus bar 15. A pin 22 projects forwardly from the plate 2 directly in the rear of arm 21 to engage said arm to prevent forcing of the lock.

To one pole of the battery 3.0 of an automobile ignition and lighting and starting system is connected a lead 31 which connects to the terminal 11 of one contact 4. A lead 32 connects the Vother pole of said battery and one brush of a motor generator 33. A lead34 is connected to the other brush of said motor generator and to the terminal 11 of the other socket contact 4. Lamps 35 are connected in parallel to the-lead 34.

By p ushing the stud 13 inwardly the pins 16 are introduced into the socketcontacts 4, closing the switch. Said pins are pulled out of said socket contacts and the switch opened by pulling said stud outwardly. By means of a key the lock arln 21 may be swung in the rear of bus bar 1'5, in which position the forward end of pin 22 is just behind the arm,` thus locking the switch open. The arm 21 may be swung out of the path of bus bar 15 by said key to unlock the switch. Y

Having described my invention, I claim:

A-switch lock including a front and a rear plate connected together, socket contacts on said reart plate, a stud reciprocatively mounted in 4said mounted on said stud, pins on said bus bar in alinenient with said socket contacts, and alock mounted on said front plate, said lock including a swinging arm adapted to be swung into the path ofsaid bus bar to prevent the introduction of said pins into said socket contacts.

In testimony whereof I affix my signature.
